<P><STRONG>Function</STRONG>
<P>
Create an Array containing constant data.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
ConstantArray DXNewConstantArray (int items, Pointer data, Type t,<BR>
                                  Category c, int rank, ...)<BR>
ConstantArray DXNewConstantArrayV (int items, Pointer data, Type t,<BR>
                                  Category c, int rank, int *shape)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
Constant Arrays provide a compact mechanism
for representing constant values in Array form.
All parameters are required:
<UL COMPACT>
<LI><TT><STRONG>items</STRONG></TT> specifies the number of items in the
Array.
<LI><TT><STRONG>data</STRONG></TT> should point to a memory location
containing the constant value to be stored in the Array.
<LI><TT><STRONG>t</STRONG></TT> specifies the type of the data:
<PRE><STRONG>
TYPE_BYTE            TYPE_HYPER        TYPE_SHORT
TYPE_UBYTE           TYPE_INT          TYPE_USHORT
TYPE_DOUBLE          TYPE_UINT         TYPE_STRING
TYPE_FLOAT
</STRONG>
</PRE>
<LI><TT><STRONG>c</STRONG></TT> specifies the category of the data:
<TT><STRONG>CATEGORY_REAL</STRONG></TT> or
<TT><STRONG>CATEGORY_COMPLEX</STRONG></TT>.
<LI><TT><STRONG>rank</STRONG></TT> specifies the rank of the data.
<LI><TT><STRONG>shape</STRONG></TT> (or the remaining
<TT><STRONG>rank</STRONG></TT>
arguments given in the <TT><STRONG>DXNewConstantArray</STRONG></TT> form)
specify the shape of the data.
</UL>
<P>
The Array created can be deleted with DXDelete.
See <A HREF="progu023.htm#HDRMEMNG">4.2 , "Memory Management"</A>.
<P><STRONG>Return Value</STRONG>
<P>
Return the Constant Array or returns <TT><STRONG>NULL</STRONG></TT> and
sets an error code.
